Lenovo wants to bring 4K to the masses with the aggressively priced US$799 ThinkVision Pro2840m monitor.

The 28-inch model will be able to display images at a 4K -- or a 3840 x 2160 pixel -- resolution, which is considered the next high-definition standard. The monitor, announced on Sunday, is one of two 4K displays being shown by Lenovo at International CES in Las Vegas this year.

Most high-definition TVs and monitors shipping today are capable of high-definition resolutions of 1920 x 1080 pixels, but the 4K resolution provides four times the depth. 4K TVs were the first to appear, and were soon followed by monitors, which are still priced above $1,000.

Lenovo also wants to quickly bring 4K to its customers as it expands its product lineup, thus the aggressive pricing, said Matt Bereda, marketing director for Lenovo's Think Business Group.

"It's an ideal device for someone working with high-end graphics," Bereda said.

The ThinkVision Pro2840m has DisplayPort, mini-DisplayPort and HDMI ports. A stand allows the monitor to be adjusted in multiple orientations. It also supports MHL (mobile high-definition link) for display of content from mobile devices.

The monitor will ship in April this year.

Lenovo also introduced the ThinkVision 28, a 4K monitor that doubles up as an Android all-in-one. Lenovo insisted that the device is first a 4K monitor and can be an Android desktop when needed. The monitor has Nvidia's Tegra processor and a stock version of Android.

The monitor will be able to run Android apps and games, and also stream 4K content if available. Wireless features allow it to access data from Android smartphones and tablets. The monitor has three HDMI ports, one Displayport and five USB 3.0 ports. The company did not provide a price, but said the monitor will ship in April.
